Many Hollywood celebrities and sports stars have appeared in high-profile advertisements for crypto firms only to later reassess their role. More than a year after the ad aired, Damon said he only did it to raise money for Water.org, a clean water initiative. Comedian Larry David, who in 2022 appeared in a Super Bowl ad for now-bankrupt crypto exchange FTX, later said he was “an idiot” to do it.

Numerous celebrities initially endorsed crypto companies but later reconsidered their involvement. Matt Damon, who promoted Crypto.com before Eminem stated his participation was intended to support a NGO. Larry David, featured in an FTX advertisement called himself an 'idiot' after being sued alongside Tom Brady, Shaquille O’Neal, and Naomi Osaka, who were accused of engaging in misleading advertising and promoting unregistered securities.
